Abstract

Verfahren zur Freilaufkompensation für ein Fahrzeug (100) mit einer Antriebseinheit (150), insbesondere ein Elektrofahrrad, wobei die Antriebseinheit (150) mindestens eine drehbare Komponente aufweist, wobei die drehbare Komponente (102, 210, 151) eine positive Drehrichtung oder eine negative Drehrichtung aufweisen kann, wobei die positive Drehrichtung dazu eingerichtet ist, ein Antriebsrad des Fahrzeugs (100) zur Vorwärtsfahrt anzutreiben, wobei das Verfahren die folgenden Schritte aufweist: Erfassung (310) der negativen Drehrichtung einer drehbaren Komponente (102, 210, 151) der Antriebseinheit (150), und Erzeugung (330) eines in negativer Drehrichtung gerichteten Motordrehmoments (M) mittels eines Elektromotors (151) der Antriebseinheit (150) bei einer erfassten negativen Drehrichtung, wobei das erzeugte Motordrehmoment (M) kleiner als ein Schleppmoment (M) des Elektromotors (151) und dazu eingerichtet ist, eine Kraft eines Fahrers des Fahrzeugs (100) zur Drehung des Elektromotors (151) zu reduzieren.Method for free-wheeling compensation for a vehicle (100) having a drive unit (150), in particular an electric bicycle, wherein the drive unit (150) has at least one rotatable component, wherein the rotatable component (102, 210, 151) has a positive direction of rotation or a negative direction of rotation the positive direction of rotation being adapted to drive a drive wheel of the vehicle (100) for forward travel, the method comprising the steps of: detecting (310) the negative direction of rotation of a rotatable component (102, 210, 151) of the drive unit ( 150), and generating (330) a negative directional motor torque (M) by means of an electric motor (151) of the drive unit (150) at a detected negative rotational direction, wherein the generated motor torque (M) is less than a drag torque (M) of the electric motor (151) and configured to apply a force of a driver of the vehicle (100) to rotate the electric motor (151).
